wcc: kind-filter type-position name resolution so a value can't shadow a same-named type (#225)

Browse Source 
resolve_typename used the kind-blind scope_lookup_prefer, so a same-named value binding (param/let) in a closer scope hid the type it shadowed, wrongly rejecting valid Hare like 'fn f(off: off)'. wwstage already separates type/value namespaces; this aligns the cstage frontend up. New scope_lookup_type skips non-SK_TYPE syms and keeps scanning, preserving same-module preference. Byte-id-neutral: the new branch fires only on the old 'unknown type' error path.
